Prepare to Boldly Go

We love our Star Trek movies (er, most of them...) and those two- and three-part episodes. However, there are still some individual Star Trek episodes that could have shined on the silver screen. Darren, Daniel, and Phillip take turns pitching episodes from 50 plus years of Star Trek that would have brought our favorite characters to feature length stories (and budgets). Which idea do you think would be the best movie? Which episode should have been made a movie?
